WebOct 4, 2011 · Abstract We examined the potential formation of chloropyromorphite [Pb5(PO4)3Cl(s)] as an experimental artifact in the physiologically based extraction test (PBET), a common surrogate method used to assess the effectiveness of in situ phosphate-based treatment to reduce Pb bioavailability in soil. Although the conditions of the PBET … WebPhosphate treatments can significantly reduce metal translocation from the roots to the shoots in the plants/crops possibly via the formation of chloropyromorphite on the cell walls of roots.

WebChloropyromorphite. Chloropyromorphite (Pb5(P0.J3Cl), used as the reference, was synthesized by slowly mixing a NaH2P04_H20 solution and a Pb(N03)2 solution undervigorously stirring. The molar ratio of Pb/P = 1.664 which is very close to the theoretical ratio of 1.667 for - pyromorphite. WebSep 2, 2006 · Comparisons of pore water Pb concentrations with chloropyromorphite and plumbogummite solubility suggest that in the phosphate-amended soils the pore waters are undersaturated in these phases, whereas several of the control soil pore waters were oversaturated, indicating the added phosphate suppressed the Pb solubility. the power of vulnerability ted talk summary https://jd-equipment.com
